Example use cases
Verify Arbitrum batch on Celestia
“Can you check whether the Arbitrum batch at Celestia height 3100500 with commitment 0xdeadbeef… was successfully committed and tell me the commitment transaction hash and its status?”
Audit Arbitrum block range in DA batch
“I need to know which Arbitrum start and end block numbers are packed into the Celestia DA batch at height 2950000 with transaction commitment 0x1a2b3c… on Arbitrum One — can you pull that for me?”
Count transactions in a Celestia DA batch
“How many transactions are in the Arbitrum batch posted to Celestia at block height 3200100 with commitment 0xfeedface…? I'm trying to benchmark throughput for that batch.”

Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/arbitrum/batches/da/celestia/%7Bheight%7D/%7Btransaction_commitment%7DWhen to prefer
Use this endpoint when you specifically need to look up an Arbitrum rollup batch that uses Celestia as its data availability layer, identified by a known Celestia block height and transaction commitment. Prefer it over generic block explorers when you need structured batch-level metadata including block range, transaction count, and commitment status across Arbitrum chains supported by Blockscout.

- Incorrect Celestia block height returns no batch found
- Malformed transaction_commitment string returns 400 bad request
